BATTERY-ZINC- SPECIEICATION forming part of Letters Patent No. 779,693,dated January 10, 1905. Application filed July 1, 1904. Serial No.214,941.

To all whom, it may concern: I

Be it known that I, FRANK J. DELAVIE, a resident of Pittsburg, in thecounty of Allei gheny and State of Pennsylvania, have invented a new anduseful Improvement in Battery- Zincs; and Ido hereby declare thefollowing to I be a full, clear, and exact description thereof.

My invention relates to electric batteries, and more especially to meansfor suspending I The bridge-piece 5 is made from sheet metal the Zinesthereof. stamped up into shape, it being provided with The object of myinvention is to provide a I downturnedflanges 6 at its edges forstrengthbattery zinc support which is simple and ening the same. Theseflanges do not extend cheap of construction, which will securely quiteto the ends of the bridge-piece, the end hold the zinc centrally in'thejar, and which portions 7 being left flat, so that the ends of willpermit the ready removal or replacement i the ribs 6 form shoulders 8,which bear against of the zinc. the inside faces of the jar, and thusprevent The Zinc of Wet batteries is usually sus- I movement of thebridge-piece and hold the The battery-jar is shown at 1, and this may beof any desired shape or size. 2 represents the Zinc, which also may beof any desired or known form, that shown in the drawings having a base 3of star shape, together with a stem 4, by means of which it issuspended. Obviously, however, these details may be varied within widelimits.

pended from a top or bridge piece resting on same centered withreference to the jar. top of the jar. In mostdevices of this characterAt its middle the bridge-piece is provided heretofore in use thebridge-piece has been with an opening 10, and communicating thererathercomplicated and expensive to make, with are lateral slots 11, at leastone such slot and in most cases the Zinc is secured thereto 1 beingemployed, although preferably two will be used, the same being arrangedon diametrically opposite sides of the opening 10 and being of lesswidth than said opening. The opening 10, with the lateral slots 11,forms, in effect, a keyhole-opening. The upper end of the Zinc or of thestem 4 thereof is provided with a pair of lateral projections or wings12, which are of such length and size that when the stem et is passedthrough the opening 10 these projections will pass through the lateralslots 11 in the bridge piece. Then by giving the zinc and bridge-piece apartial turn relative to each other the projections 12 on the Zinc willvrest upon the upper face of the bridge-piece and be supported thereby.To prevent the Zinc from turning when so held, and thus from droppingdown into the jar, I provide on the Zinc one or more projecting nibs 13,preferably located just underneath the projections 12, so that they willalso pass through the lateral slots 11 in the bridge-piece, these nibsbeing arranged to take into notches, openings, slots,or depressions 14,formed in the bridge-piece. The notches or openings 14 are not ofsuflicient size to allow the projections 12 to pass through, and as aconsequence the zinc will be supported by the projections 12 and will beheld against turnby means of a screw or nut or other connecting meanswhich require time for removal and which, due to rust and the like, areoften I difficult to loosen. Many zinc-supports also I had the fault ofpermitting the zinc to get out of center in the jar.

My zinc-support is intended to obviate all of the foregoing objections;and it consists, generally stated, in a bridge-piece composed of astamping of sheet metal provided with shoulders near its ends to holdthe same centered with reference to the jar and provided at its middlewith a key-slot or similar opening to receive the stem of the zinc, thelatter being provided with lateral projections or wings which can bepassed through the keyslot in the Zinc and then by giving it a partialturn will rest upon and be supported by the upper face of thebridge-piece. In the accompanying drawings, Figure 1 is a perspectiveview of a battery provided with my improvement. Fig. 2 is a detailsectional view through the Zinc-support and showing the upper portion ofthe Zinc. Fig. 3 is a perspective view of the bridge-piece. Fig. 4 is asimilar view of a modified form of bridgepiece, and Fig. 5 is atransverse section showing the modification.

ing by the nibs 13. It is not necessary that the notches 14: be cutentirely through the bridge-piece; but they may be formed merely asseats or depressions 14; therein, as shown in Figs. 4: and 5, forreceiving either the nibs 13 or the lateral projections 12 themselves,the latter being illustrated in Fig. 5.

The bridge-piece described is very simple and cheap to manufacture. Itcan be formed from sheet metal of the required thickness by simpledie-stamping, a single operation of the dies serving to cut and turn theflanges 6 and to punch the opening through the same for the stem of thezinc. The edge flanges 6 stiffen the brid ge-piece, so that very lightsheet metal may be employed, and at the same time the ends of saidflanges form shoulders to hold the bridgepiece centered on the jar. TheZinc and bridgepiece can be readily assembled or disassembled by merelygiving them a partial turn relatively to each other, it not beingnecessary to manipulate nuts, screws, or the like. At the same time thezinc is securely held and cannot rotate, so that there is no liabilityof it becoming displaced and dropping down into the jar.

It will be obvious to those skilled in the'art that variousmodifications can be made in the details of the invention withoutdeparting from the spirit thereof.

hat I claim is 1. In an electric battery, the combination of ajar, abridge-piece therefor provided with a key-slot opening therethrough, abatteryzinc having a stem provided with a lateral projection orprojections arranged to pass through the keyhole-slot of thebridge-piece and when given a partial turn to rest upon the upper facethereof.

2. In an electric battery, the combination with a jar, of a bridge-piecetherefor provided with an opening therethrough and two slots extendinglaterally therefrom, and a batteryzinc having an end adapted to passthrough the opening in the bridge-piece and being provided with twolateral projections or wings adapted to pass through the lateral slotsin the bridge-piece and when given a partial turn to rest upon the upperface thereof.

3. In an electric battery, the combination with the jar, of abridge-piece therefor provided with a key-slot opening therethrough andwith a seat or seats in the upper face thereof, and a battery-Zinchaving a stem arranged to pass through the opening in the bridge-pieceand provided with a lateral projection or projections adapted to passthrough the hey-slot in the bridgepiece and when given a partial turn torest in the seats formed in said bridge-piece. I

4. In an electric battery, the combination with a jar, of a bridge-piecetherefor provided with an opening therethrough and with a pair oflateral slots communicating with said opening and also with a seat orseats formed 5 therein, and a battery-zinc provided with a stem arrangedto pass through the opening of the bridge-piece and having a pair oflateral projections or wings arranged to pass through the lateral slotsof the bridge-piece and when given a part turn to rest on the uppersurface thereof, and also having a nib or nibs arranged to engage theseat or seats formed in said bridge-piece.
